  • Patent number: 4560864
    Abstract: In the device disclosed, an image formed by an optical system is scanned by an image sensor composed of independently arranged photoelectric transducing elements to produce an image scanning signal. A detecting circuit detects the variation of the brightness between the adjacent image elements as a measure of the sharpness of the image and the focus of the optical system. The focus detection accuracy is improved by non-linear transformation of the brightness variation signal with a non-linear transformation circuit that weighs the brightness variation signal on the basis of the signal level. A signal forming circuit detects the difference between the outputs of transducing elements and adds the differences to produce a comparator signal when a predetermined relationship is reached between the sharpness indication and the addition signal.

  • Patent number: 4547663
    Abstract: A focus detecting apparatus is disclosed which includes a focusing optical system for forming an object image on a predetermined focal plane and photoelectric devices disposed before and behind the focal plane at substantially equal distances from the plane. The photoelectric devices detect the focus states of the object images formed thereon respectively. The focus state of the object image on the focal plane is detected depending on whether or not the focus states on the photoelectric devices are equal to each other. According to the invention such a focus detecting apparatus further includes a mask for gradually decreasing the quantity of light incident upon the photoelectric devices in the direction away from the center of the incident beam. Under the action of such a mask, the focus states of object images before and behind the predetermined focal plane at substantially equal distances from the focal plane are made approximately equal to each other.

  • Patent number: 4529304
    Abstract: The disclosed apparatus determines optically whether an object is located within a first range of distances from the apparatus or a second range of distances from the apparatus. A radiation projecting arrangement projects a beam towards the object and a receiving arrangement disposed a predetermined distance transverse to the object direction receives the radiation reflected from the object. A pair of radiation sensors in the receiving arrangement each produce an electrical output corresponding to the received radiation. A circuit responds to the outputs of the sensors to determine whether the object is located within a first range or a second range. The circuit arrangement connects the radiation sensors so as to subtract their outputs, and one of the sensors is provided with a more extensive radiation receiving area than the other. This extends one of the range of distances.
